PERMANENT WAVE CLASP Filed Oct. 3. 1931 Myrtle Lin/dang ATTO RNEY Patented Jan. 24, 1933 P AT E NT l- F F I CE MYRTLE LINDSAY, 0F DALLAS, TEXAS PERMANENT WAVE CLASP Application filed October 3, 1931.

This invention relates to hair waving devices and equipment and especially to so called permanent waving in which the hair is squared, wound about core and inserted into an electrically heated oven after certain treatment. The present invention has for its principal object to provide a clasp adapted for application to the lock of hair next to the patients scalp to prevent excessive heating and consequent discomfort to the patient undergoing the treatment.

Another object of the invention resides in the provision of an improved permanent wave clasp so designed as to positively insulate the scalp against severe heat by the incorporation of heat absorbing and insulating materials which are in direct contact with the scalp, the clasp proper being held thereby away from the scalp and forms securing means.

Still another and important object of the invention resides in the provision of a clasp as designated which is not only very effective in bringing about the advantages above mentioned, but likewise affords a means for saving considerable time and effort in the waving operation which consumes a great deal of time and is uncomfortable to the patient.

lVith these objects as paramount, other objects and advantages, as well as certain salient features of construction and operation will become manifest as the description proceeds, taken in connection with the accompanying drawing, wherein:

Figure 1 represents an enlarged perspective view of a clasp constructed according to the present invention.

Figure 2 is a plan view showing the layers of insulating material broken away in parts.

Figure 3 is a side elevational view of the improved clasp.

Figure at is an end elevational view thereof, and

Figure 5 is asectional View on lines 55 of Figure 3.

Continuing with the drawing, the clasp proper is comprised of two members 1 and 2, pivotally connected together at a. Each of the members are so formed as to define finger grips 3, by which the same are relatively Serial No. 566,710.

opening, dependent upon the size of the lock of hair to which the clasp is applied.

The ordinary methods of securing the hair for the application of the oven, 21. series of heat resisting elements of disc-like shape having central openings are applied, the said lements being split from the center out in order to facilitate their application. After this operation, the metal clasp is applied to hold the heat resisting elements in position.

It frequently occurs that the heat resisting elements are displaced, allowing the edges of the clasp to come into contact with the scalp, burning the latter and causing extreme discomfort to the patient. An added disadvantage in the old methods of insul-ating the clasp from the scalp is the time consumed in application thereof preparatory to baking. During the preparation, the patient is undergoing considerable strain and it is the object of the operator to minimize asSO much as possible the time in making preparations and completing the work.

Accordingly, the clasp shown in the drawing has afiixed thereto laminations of heat absorbing and heat resisting materials which are a permanent part of the clasp by being affixed thereto by rivets or brads 6.

This important feature of the invention very obviously reduces the operations from the maximum of four in the application of each clasp to one as the minimum.

Primarily, a layer of paper fiber 7 is applied directly to the clasp members, and

which fiber, as well as the other layers of material to be later referred to, is cut to conform with the shape of the members 1 and 2, however, the fiber edges are flush with edges of the clasp members, While the other layers of material which consists of a layer of felt 8 and one of rubber 9 overlap the edges of the fiber and clasp. This prevents any possibility of the fiber or metal coming into contact with the flesh of the scalp.

It will be noted that the thin rubber cov- 5 ering 9 is cemented rather than riveted onto the felt layer 8, which precludes the possibility of the heat, conducted by the rivets 6, coming into direct contact with the scalp.

Obviously, the improved clasp is very ef- 10 fective in reducing to a minimum degree the labor and time required in permanent waving, as well as insuring against displacement of the heat insulating elements and allowing the clasp to come into contact with the scalp after having been heated by the oven.

Manifestly, the construction shown is capable of considerable modification and such modification as is considered within the scope and meaning of the appended claim is also considered within the spirit and intent of the invention.

lVhat is claimed is: In a clasp for use in permanent waving, the combination comprising a pair of sub stantially curved clasp members pivoted together for relative movement and shaped to define a circular area to receive a lock of hair, one of said members having a projection arranged to engage with one of a series of recesses in the other of said members for locking said members together, fiber heat insulating members secured to the undersides of each of said clasp members and Whose edges are disposed flush with the edges of said clasp members, a felt disc secured to the underside of said heat insulating members of greater diameter than the overall diameter of said clasp members whereby to overreach the edges thereof, a rubber disc affixed to said felt disc and of a diameter equal thereto and means to effect opening and closing of said clasp members.

In testimony whereof I afliX my signature.
